When a billiard ball collides in an elastic head on collision with a second stationary identical ball after the collision?

When a billiard ball collides in an elastic head on collision with a second stationary identical ball after the collision?

1 Expert Answer Since the billiard balls are of equal mass, when this situation occurs in an elastic collision all of the momentum from the first ball will be transferred to the second ball giving a final velocity of the second ball of 12 m/s.

What happens when two billiard balls collide?


What type of collision is to billiard balls collide?

In the given case, the forces involved are conserved. This is because they depend on the separation between the centres of the billiard balls. Hence, the collision is elastic.

What type of collision was two moving billiard balls collide and bounce off one another moving in opposite directions?

After an elastic collision, the two billiards balls bounce off in opposite directions at equal speeds. In this case, both the momentum and kinetic energy stay the same before and after the collision. The kinetic energy of the objects remains constant after an elastic collision.

What happens when 2 identical masses collide in an elastic collision?

Two objects that have equal masses head toward each other at equal speeds and then stick together. The two objects come to rest after sticking together, conserving momentum but not kinetic energy after they collide.

When two identical masses collide with each other in elastic collision what will be the velocities after collision?

For a head-on collision with a stationary object of equal mass, the projectile will come to rest and the target will move off with equal velocity. Hence, the velocities are interchanged i.e. the speeds are interchanged which in turn interchanges the momentum.

What happens when a moving ball collides with a stationary ball?

Due to the collision of the moving billiard ball to the stationary ball, the stationary ball will be set into motion. This happens because of the momentum transfer from the moving ball to the stationary ball. The initial momentum of the moving ball will be shared by both balls after the collision.

What are 3 types of collisions?

  • Perfectly elastic collision.
  • Inelastic collision.
  • Perfectly inelastic collision.

When a billiard ball collides with another billiard ball at angle is momentum still conserved?

In other words, Ball 1 exerts the same force on Ball 2 that Ball 2 exerts on Ball 1. In this way, momentum is conserved, so that for any amount of momentum that Ball 2 gains, Ball 1 loses. That’s just Newton’s third law. Since they have the same mass, Ball 1 will decelerate at the same rate Ball 2 accelerates.

When two billiard balls collide each other at equal speed?

This is given by the law of conservation of momentum. When the balls have the same mass and are going to make a head on collision, as the final momentum will be equal to the initial momentum the objects will rebound in the opposite directions with the same speed as that before the collision.

Is momentum always conserved?

Momentum is always conserved, regardless of collision type. Mass is conserved regardless of collision type as well, but the mass may be deformed by an inelastic collision, resulting in the two original masses being stuck together.

Is two billiard balls colliding an example of elastic collision?

Elastic collision; Sample: Two billiard balls collide and then move separately after the collision. Two billiard balls of equal mass are traveling straight toward each other with the same speed. They meet head-on in an elastic collision.

When two objects collide what is the same before and after the collision?

In collisions, it is assumed that the colliding objects interact for such a short time, that the impulse due to external forces is negligible. Thus the total momentum of the system just before the collision is the same as the total momentum just after the collision.

What happens after a perfectly inelastic collision between two identical balls moving with the same speed?

After a perfectly inelastic collision between two identical balls moving with the same speed in different directions, the speed of the combined mass becomes half of their initial speed.

What type of collision occurs when two objects collide and bounce away from each other after the collision?

If the objects bounce apart instead of sticking together, the collision is either elastic or partially inelastic. – An elastic collision is one in which no energy is lost. – A partially inelastic collision is one in which some energy is lost, but the objects do not stick together.

What is the expression for the final velocities of two bodies after head on elastic collision?

On This basis, Derivation in One dimension is shown in attachment. The body of mass m₁ is moving with the velocity u₁ and body of mass m₂ is moving with velocity u₂, after the collision there velocity became v₁ and v₂. The Final Result is, v₂ – v₁ = u₁ – u₂.
